1 Claim. 1

This invention relates to suspension means for mounting the chassisframework of a vehicle upon the braked wheels thereof, particularly whensuch Wheels are closely spaced at each side in tandem relationship.

The present invention is concerned with brake operating mechanisms andmeans for mounting them within the suspension, especially where thesuspension embodies a relatively rigid arm of substantially invariablelength or a relatively rigid walking beam carrying stub axles.

The subject matter of this application is divided out of my copendingapplication, Serial Number 626,025, filed November 1, 1945, now PatentNo. 2,492,126, granted December 20, 1949.

It is the primary object of this invention to devise a novel and usefulcombination of a suspension arm and operating mechanism for the brake ofa wheel that supports the arm.

Another important object of the present invention is to provide animproved brake actuating mechanism operable from power means mounteddirectly upon a wheel suspension element.

A further object resides in the provision of a novel and useful spidermountable upon a stub axle and carrying elements operable to actuate thebrake of a wheel carrying said stub axle.

The foregoing and other objects of the present invention should clearlyappear from a study of the following detailed description when taken inconjunction with the accompanying drawing, wherein:

Fig. 1 is a top plan view, in partial section, of a preferred embodimentof the invention, brake actuating mechanism being shown only at one endof the beam;

Fig. 2 is an end view, likewise in partial section; and

Fig. 3 represents a side elevational view of the same device with powerunits and linkages added.

With continued reference to the drawing, there is shown a rigid, hollowwalking beam 5 having integral ofiset ends 6, between which there is ahub 1 dividing it into a pair of sloping arms and designed to bepivotally received by a shaft or sleeve member for support of a vehiclechassis. Normally this member (not completely shown) will take the formof a jack-shaft assembly H mounted transversely of the chassis inunsprung relation thereto.

Stub axles 8 have enlarged portions 9 set securely into sockets in thebeam ends 6, and between their ends these axles have surfaces 12 for aspecial purpose presently to be made apparent.

In order to render the beam more sturdy and to afford better support forthe jack-shaft assembly, a plate [3 may be welded to the bottom of thebeam below the hub l to provide a platform that extends towards thevehicle center line; and this plate may be reenforced by two furtherplates 14 alongside thereof and likewise preferably secured in positionby welding. To the extended end of the platform there is bolted orotherwise secured the base of a sleeve member l5 so that the bearingportion thereof is aligned with the hub I.

To each plate M (or in the absence thereof, directly to the beam) thereis rigidly secured a bracket l6, and to the inner or opposed faces ofthe brackets there is secured a pair of conventional power units I! forthe purpose of actuating the brakes of the wheels to be mounted on theaxles 8. The units I! have suitable connections (not shown) to a powersource on the vehicle. Each power unit linearly actuates a rod I8 thatextends towards an end of the beam into pivotal interconnection with thelower end of a lever Hi just below one of the stub axles.

The upper end of each lever I9 is screwed into a socket 20 that isaffixed, by key or otherwise, to one end of a shaft 2|. The latter isjournaled through a lug 22 welded to the walking beam and thence throughone eye 24 of a spider 23,

the hub 25 of which is tightly fitted upon the appropriate stub axlesurface I2. The spider has two further integral eyes 26 to which theproximate ends of a pair of brake shoes (conventional and not shown) maybe pivotally connected. The other ends of the shoes are intended to beseparated in known manner by an S-shaped cam C when braking power issupplied to the motors H.

It will be seen that the disclosed structure is compact and so arrangedas to require space not otherwise usable, and that it affords facile andvery accurate brake operation.

Obviously, some changes in design may be made within the scope of theinvention, also that the actuating mechanism might be applied to asingle suspension arm pivotally connected at one end to the vehicleframe. Therefore, I wish to be limited in customary manner only areasonably liberal interpretation of the appended claim.

What is claimed is:

In combination with a rigid walking beam having a central pivotal hubintegral with a pair of downwardly sloping arms, and a stub axle rigidlycarried by the end of each arm: a pair of individual brackets securedsymmetrically to the bottom of said beam within the crotch formed bysaid sloping arms; a. power motor mounted upon 3 4 each bracket andapproximately within said crotch; a spider mounted upon each stub axleto UNITED S ATES PATENTS serve as an intermediate support for mechanismNumber Name Date actuated by its associated motor; and an cperag- RogersNov. 8 1932 ating linkage connected between each motor and 5 1,908,223Dotson May 9, 1933 its associated mechanism 1,925,536 Judd Sept, 5, 1933GUSTAVE COLLENDER- 2,239,286 Freitag Apr. 22, 1941 2,311,252 Reid Feb.16, 1943 REFERENCES CITED 2,343,872 Low Man 14, 1944 The followingreferences are of record in the 10 2,417,690 Keller, Jr. Mar. 18, 1947file of this patent: 2,459,372 Fraunfelder Jan. 18, 1949
